WiFi Surveys & Optimisation London

Fast, reliable Wi‑Fi doesn’t happen by accident — it’s engineered.

If your teams are battling dead zones, slow speeds, unreliable video calls or “it works everywhere except the meeting rooms”, a professional Wi‑Fi site survey gives you the truth: what’s happening in your building, why it’s happening, and the most cost‑effective way to fix it.

Call 0333 900 0101 or email sales@network-data-cabling.co.uk to arrange a Wi‑Fi survey.

A Wi‑Fi site survey measures and models your wireless coverage and real‑world performance. It identifies dead zones, interference and capacity bottlenecks, then recommends access‑point placement and configuration changes so your network meets your coverage, speed and device requirements.

• Most ACCL Wi‑Fi surveys include:
• Floor‑by‑floor heatmaps (coverage and signal quality)
• Interference and channel congestion analysis
• Capacity planning for high‑density areas (meeting rooms, classrooms, auditoriums)
• Recommended access‑point locations, mounting guidance and backhaul (cabling/PoE) requirements
• A prioritised optimisation plan (quick wins vs. upgrade options)

Our Wi-Fi site surveys focus on;

Wi-Fi Performance and Capacity

We look beyond “is there a signal?” and focus on whether users can actually work. That means measuring how your network behaves where it matters most — meeting rooms, desk zones, reception areas, high‑traffic corridors and any areas supporting voice, video or line‑of‑business systems.

We assess:

• Coverage and signal quality (so connections stay stable)
• Contention and capacity (so performance doesn’t collapse at peak times)
• Roaming behaviour (so calls don’t drop when people move around the building)
• Backhaul constraints (cabling, PoE budgets, switching and uplinks) that can limit Wi‑Fi performance

Security, Resilience and Compliance

Wireless is part of your security perimeter. A strong survey doesn’t just optimise performance — it highlights security gaps and design risks so you can reduce exposure.

We can review:

• Guest vs. staff vs. IoT segmentation requirements
• Authentication approach (e.g., WPA2/WPA3, captive portal where appropriate)
• Coverage leakage (signal bleeding outside the building) and how to reduce it
• Design resilience for critical areas (redundancy, channel planning and configuration hardening)

Working with Your Space

Buildings dictate Wi‑Fi outcomes. Our surveys account for your environment so the design works in the real world — not just on a spec sheet.

Our survey reporting can include:

• Heat Maps: colour‑coded coverage maps that show signal quality by area and floor
• Construction and Layout Factors: materials (concrete/metal/glass), partitions, racking, plant rooms, ceiling heights and reflective surfaces
• Floor Plans and Mobility: how people move through the space and where they need seamless roaming
• Outdoor areas (where required): yards, terraces, loading bays and external guest spaces

What’s included in an ACCL Wi‑Fi site survey

A typical Wi‑Fi survey and optimisation engagement includes:

• Discovery and requirements capture (users, devices, critical areas, growth plans)
• Site walkthrough (access constraints, mounting options, comms room locations and backhaul routes)
• Wireless measurement and/or modelling (depending on survey type)
• Interference and channel environment assessment
• Capacity and density review for high‑usage areas
• Security review inputs (segmentation and authentication requirements)
• Report creation and recommendations workshop (so your team knows exactly what to do next)

What you receive (deliverables)

You receive an actionable report you can hand to an internal IT team, a third‑party MSP, or keep with ACCL for implementation. Deliverables can include:

• Executive summary (plain‑English: what’s wrong and what to do)
• Heatmaps (coverage / signal quality / interference) by floor
• Recommended access‑point locations with mounting notes
• Channel plan and configuration recommendations (where applicable)
• Capacity guidance for busy zones (meeting rooms, open plan, events)
• Backhaul requirements (cabling/PoE/switching considerations)
• A prioritised optimisation plan (quick wins first, then upgrade path)
• Optional bill of materials (AP models, controllers, brackets) if you want ACCL to supply and install

Why you need a Wi‑Fi site survey

A Wi‑Fi survey prevents guesswork. It’s the difference between “buy more access points” and “engineer the right network for this building”. Key reasons businesses book surveys include:

Internet of Things ready

IoT devices increase demand and create new coverage requirements (cameras, sensors, printers, access control and building systems). A survey ensures the network supports these devices without compromising staff performance.

Ability to scale

If headcount, device counts or floorplans change, your Wi‑Fi needs a design that scales. Surveys create a roadmap you can build on — not a fragile setup that breaks with every change.

Eliminate black spots

Materials like concrete, metal, glass and dense partitions can kill RF performance. We map these realities so the final design delivers consistent coverage — not pockets of frustration.

Support multiple devices per user

Modern workplaces are BYOD by default: laptops, mobiles, tablets and specialist devices. Capacity planning ensures your network can handle real device density.

Outdoor coverage (where required)

Outdoor spaces have unique challenges (interference, mounting, weather and distance). If your business needs yard, terrace or loading‑bay coverage, we include the right approach from day one.

Improve network security

Surveys highlight weak points, misconfigurations and risk areas. The output supports better segmentation and a stronger wireless security posture.

How to prepare for the survey

To make the survey faster and the recommendations more accurate, it helps to have:

• Floor plans (if available) and any recent layout changes
• A list of problem areas (rooms, floors, times of day)
• Approximate device counts (staff + guests + IoT)
• Any network constraints (cabling, comms rooms, PoE limits)
• Access requirements for secure areas or out‑of‑hours working

Pricing factors (what affects cost)

Wi‑Fi surveys are scoped. Typical cost drivers include:

• Building size, number of floors and complexity of layout
• Whether you need a predictive design, on‑site testing, or both
• Density and performance requirements (e.g., events, education, hospitality)
• Whether outdoor areas are included
• Reporting depth (executive summary only vs. full technical annex)

Q: Do you survey outdoor areas too?

A: Yes. Outdoor coverage can be included, with design considerations for mounting, weather exposure, interference and secure backhaul.

Q: What deliverables will we receive?

A: You receive an actionable report with heatmaps, recommended access‑point locations, interference findings, capacity considerations and a prioritised optimisation plan. If you proceed with installation, we also provide as‑built documentation and validation results.

Q: Can you help us implement the recommendations?

A: Yes. ACCL can deliver the remediation end‑to‑end, Wi‑Fi installation, structured cabling to access points (often PoE), configuration, optimisation and post‑install validation testing.

Q: Do you support Wi‑Fi 6E / Wi‑Fi 7 planning?

A: Yes. We plan around coverage and capacity targets first, then recommend the most cost‑effective standard and hardware for your use case, including 6 GHz planning where appropriate.
